Device for absorbing atmospheric dust in classroom

Abstract

The invention discloses a device for absorbing atmospheric dust in a classroom. The device for absorbing the atmospheric dust in the classroom comprises a blackboard. A dust absorption mechanism is arranged on one side of the blackboard, and a positioning mechanism is arranged at the lower end of the dust absorption mechanism. The dust absorption mechanism is connected with a dust collecting mechanism, and an origin mechanism is arranged on one side of the blackboard. The dust absorption mechanism comprises a transverse slide way, a guide groove, a baffle block, a movable table, a guide sliding block, a sliding mechanism, an air draft fan, an air draft channel, a blocking cover, a circular through hole, an air draft pipe, a telescopic hose, a conical flaring, a fixing ring, a multistage electric telescopic rod and a connecting ring. The positioning mechanism comprises a square groove, a tension sensor, a first signal transmitter, a connecting rope, a supporting plate, an intercepting plate, an intercepting groove, a long strip penetrating hole, a blackboard eraser, a small groove and a pressure sensor. The dust collecting mechanism comprises a collecting box, an air outlet, a collecting inlet, a telescopic collecting pipe, a fixed column, a connecting column and a sliding ring. A controller is arranged on one side below the collecting box. The device for absorbing the atmospheric dust in the classroom has the beneficial effects of a simple structure and high practicability.

Description

technical field [0001] The invention relates to the field of atmospheric control, in particular to an atmospheric dust absorption device in a classroom. Background technique [0002] It is often necessary to wipe the blackboard in the classroom, and the dust that is wiped is scattered and flutters, causing air pollution, and the students studying in the classroom breathe the air with dust, which is easy to affect their own health. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems, and has designed a kind of atmospheric dust absorption device in the classroom. [0004] To achieve the above object, the technical solution of the present invention is a classroom air dust absorption device, including a blackboard, the blackboard is fixedly installed on the front wall of the classroom, a dust suction mechanism is provided on one side of the blackboard, and the lower end of the dust suction mechanism There is a posit...
